GEORGE HAYES, OF NEW YORK, N. Y.

METALLIC SKYLIGHT.

SPECIFICATION forming part of Letters Application tiled July 24, 1882.

To all whom it may concern:

Be it known that I, GEORGE HAYES, a resi' dent of the city, county, and State of New York, have invented a new and useful Improvement in Metallic Skylights, of which the following is a specification.

My invention consists in a supplemental base-frame, u p-on which theskylight-trainerests or to which it is attached, the supplemental frame provided with one or more ventilating devices formed therein, consisting of a boxed or inclosed chamber apertured outwardly and inwardly, and having a regulating valve, slide, or damper covering, when closed, one of the said apertures, and a perforated metallic plate covering one or both of the openings when desired, the object being, primarily, to obtain secure ventilation at the base of the skylight, and thereby dispense with the ordinary ridgeventilator, occupying usually a space centrally in the light, causing more or less obstruction thereto, although my new base-ventilator may be used in conjunction with a ridgeventilator where desired and the circumstances of the case render it desirable to use them together in the same structure; and, secondarily, to provide ventilation at the base otthe skylight siructure,whicb, while atiording ample ventilation, will be storm-proof and weather-tight, thereby avoiding leakage or drip, It may be formed of one piece with the base-frame proper of the skylight, or of separate pieces united thereto byany suitable means. The ventilators may be of any suitable length and any suitable number, and located at the sides or ends or both sides and ends of the skylights, and are adapted to be used with any form of sky1ight.flat, doublepitched, or hipped lights.

In the accompanying drawings, Figure l is a view in perspective of a skylight structure provided with my supplemental base-frame, showing ventilators therein. Fig. 2 is an outside view, in perspective, of a ventilator and portions of supplemental frame. Fig. 3 is an inside view, in perspective, of a ventilator, showing sliding valve. Fig. 4 is a vertical section through skylight, base-frame, supplemental frame, ven tilator-box, valve, and perforated plate covering ontside aperture to the ventilating'chamber.

Patent No. 277,485, dated May 15, 1883.

(No model.)

A represents a skylight structure; B, the base frame thereof, supporting the bars or rafters thereof.

0 represents the supplemental base-frame, its lower part, G, resting on the wooden curb of the building-roof.

I) represents the box-ventilators, arranged in and forming a part of the su 'iplemental base-frame, the chamber therein marked E, the outer aperture F, and the inner Gr.

At H is shown the valve, slide, or damper used for regulating ingress or egress of aircurrents.

I represents a perforated metal plate protecting the opening from indriving snow, sleet, or rain, Sac. This perforated plate I is made of sheet metal, and its object is to break up the force of the wind, the perforations therein being small enough to prevent entrance of birds or insects, admitting only air. The force ofthe wind being broken, any mist or vapor from snow or rain can only reach the interior of chamber E, whence it escapes backward through lower apertures of perforated plate I to the outer air, over thelower part ofbase O, and away from the skylight. Vireganze may be used instead of perforated plate, if desired, the object being to obstruct the entrance of air as little as possible consistent with the breaking up of snowflakes and rain-drops into mist or vapor. This perforated plate or apertnred shield may be dispensed with whenever proper, so as to admit air more freely, as might be found desirable in localities where not troubled with snow-storms or driving rains.

The regulating device may be hinged or pivoted and adaptedfor turning to open or close the opening, as in Fig. 3, or made to slide in grooves or otherwise, as shown in Fig. 4.

I do not restrict myself to the shape or style of valve or damper, as it maybe curved or otherwise, and secured by any suitable means hinged, pivoted, or arranged to operate in any suitable manner.

What I claim as new, and desire to secure by Letters Patent ot theUnited States, is-- 1. A supplemental base'frame fora skylight, between skylight and curb, provided with chamber E, inclosed by boxing D, the outer walls thereof apertured, as at F, and the inner I reams;

walls apertured, as at G, and provided with asky1ightstructure,) and provided with valve,

regulating valve, slide, or damper H, substanslide, or damper H, substantially as shown and tially as shown and described. described.

2. A ventilator consisting of chamber E, GEO. HAYES. its outer walls apertured, as at F, and inner Witnesses: wallsthereof, as at G, constructed in and form- RICHARD H. REILLE,
